3 Terms and definitions
The following terms and definitions apply to this document.
3.1
Pervaporation Pervaporation
The separation of the components is achieved by the difference in the rate of dissolution and diffusion of the liquid mixture components in the membrane.
[GB/T 20103-2006, Definition 6.2.7]
3.2
Vapor penetration vapourpermeation
The separation of the components is achieved by the difference in the rate of dissolution and diffusion of the components of the vapor mixture in the membrane.
[GB/T 20103-2006, Definition 6.2.8]
3.3
Pervaporation vaporization membrane pervaporationdehydrationmembrane
Preferential permeation of water through the gasification membrane.
3.4
Flat membrane membrane flatmembrane
